When it is very light acceleration it is white, when the turbo kicks in and under hard acceleration you get black smoke. No one seems to know what it is. I have been to delphi dealer as well as Ford dealer and none of them can find a fault.
Thanks for your reply
Tom

same amount of smoke as before when driving injecters was fitted at a delphi dealer. before they was fitted if u started when cold there would lots of white smoke a lot but now none and sounds a lot quieter to ps with new codes and coded to car

I would go back to that Ford dealership . if its doing what you say then the motor definitly has a fault .. either in the turbo . pipe work or the injection ..or the egr .. but eitherway that dealership is just being lazy about it .. the motor has a fault .. it smoking and not performing . i would go back and demand they diagnose the motor properly . that is not satisfactory service from a main dealership. IF howeve you dont get satisfaction the i would try blanking the egr . first anyway . it will probably throw a dash light but thats no harm it can be cleared because it wouldent be the first time a new egr .was fitted and found faluty. s

Op, you need to blank the EGR for greatest reduction in smoke under hard acceleration. Mine was worst on cold mornings after a few miles warming up on twisty back roads and then joining a dual carriageway. Did this for 70k miles plus, then fitted a GW blanking plate, there's still a hint on colder mornings but nothing like it was previously.

There's no need to tell Fruad about the blanking of the EGR (remove blank if you go back). Blank EGR, use a good fuel additive, run a couple of tanks through the thing, run it for 10 miles plus at 2k rpm plus to clear out the cr@p and then see if it smokes. I wouldn't be too concerned about smoke if the car is running OK.
